I Application filed December 15, 1918. Serial No. 344,878. v

To all whom it may concern:

Be it known that I, WALTER E. BEYER, a citizen of the United States, residing at Indianapolis in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Gas-Tank Alarms, of which the following is a specification. I

This invention relates to alarms, more especially to one adapted to be attached to liquid containing tanks, such as the gasolene tanks of motor cars. It is among the objects of this invention to produce a device of this character which is compact, simple in construction, and easily attached to and removed from the tank.

In carrying the objects of my invention into effect, I provide a screw cap for the tank and mount upon the cap a mechanism for sounding an alarm operated preferably by clock work, although electrical or other equivalent means may be used, adapted to sound the alarm when the liquid level falls to a predetermined point. Specifically, I form guiding means on the screw cap an rovide a float, which is guided thereby.

lock work is also secured to the cap and to the float, which is adapted to release a hammer to allow it to strike a' bell whenthe float drops to a predetermined level.

Referring to the accompanying drawings, forming a part hereof and in which similar reference characters denote similar parts,

The single figure illustrates a vertical section through a tank having my device attached thereto, some parts being shown in elevation.

To the top. 1 of the tank 2 is secured a screw threaded member 3 into which the correspondingly threaded cap 4 having wing extensions 5 is adapted to be inserted. Secured to the under side of the cap are guide rods 6 and 7 of any desired form, the

guide rbd 7 being preferably hollow for a purpose indicated below. i

A float member 8 operates within and is held in place by the guide rods and has a stem formed in two sections 9 and 10 and secured together at 11 in order that the height of the float may be adjusted at will. The upper end of the stem is secured at 12 to a locking device 13 which is adapted to lock the pawl member and to release the same upon the dropping of the float 8 to a predetermined point.

A bell member 14 is secured to the spring 15 which is fixed to the cap or closure 14 and is intended to be used not only for sounding the alarm but also for winding the spring which provides the necessary force for operating the mechanism 16 which is of the ordinary clock work type, causing the actuation of the hammer 17.

The hollow guide rod 7 has its lower end 20 1n open communication with the tank and an opening 21 is provided in the upper end of the guide rod in order to prevent a vacuum forming therein. A float 22 is movably secured therein and has a stem 23 hearing a serles of graduations indicating the amount of liquid in the tank. The uppermost end of the stem 23 is provided with a,

screw threaded member adapted to be threaded into opening 25 of the cap 4 when this device isin inoperative position.

To operate the device he tank is filled with liquid and the cap screwed in place. The bell member 14 is rotated by the fingers in order to wind the spring 15 to the proper (1 degree. When the liquid level falls below the predetermined point the float 8 will drop, carrying with it the lock member 13, releasing the clock work 16 and allowing the hammer to strike the'bell, thus sounding an alarm warning the driver of the car that his gasolene is low. The float 22 and associated parts are capable of indicating at any desired time the amount of liquid in the tank.

cured at one end to the inner wall of the closure and adapted to engage a movable controlling the operation of the alarm,

guides on said cap for guiding said float, one of said guides being hollow, a float therein, a stem carried thereby, the upper end of said stem having a threaded portion adapted to be screwed into said cap.

a float connected to said locking device and controlled by the liquid contents of the tank adapted to release said locking device from the clockworks, guides for said float, and means associated-With one of said guides for manually determining the liquid content of said tank, substantially as set forth.

In witness whereof, I have hereunto set I my hand and seal at Indianapolis, Indiana this 13th da of December, A. D. nineteen hundred an nineteen.
